For all of you who watched the movie 2012, and have been reading about the prophecies, here’s some interesting news. The world may not end this year.The walls reveal the oldest known astronomical tables from the Maya. Scientists already knew they must have been keeping such records at that time, but until now the oldest known examples dated from about 600 years later.

Astronomical records were key to the Mayan calendar, which has gotten some attention recently because of doomsday warnings that it predicts the end of the world this December. Experts say it makes no such prediction. The new finding provides a bit of backup: The calculations include a time span longer than 6,000 years, meaning it could extend well beyond 2012.
